Instance template parameters should not be made available to static methods – this was a flaw in my implementation, now fixed. If/when generics are available at the language level this can be re-evaluated.

/**
 * @template T
 */
class C {
    /**
     * @param T $t
     */
    public static function foo($t) : void {}
}

Expected: some sort of error (in Psalm for now it just treats it as a missing docblock class, you may want something more helpful).
